SSP brand Series S stainless steel rotary lobe pumps, from Alfa Laval
Pumps Limited, operate at the heart of process industries worldwide.
Series S pumps fulfill a wide range of application requirements through-
out Chemical, Food, Pharmaceutical and other related industries.
Handling from low to high viscosity pumped media the characteristic
smooth, low shear pumping action is ideal for delicate media and where
organic solids in suspension, creams, froths, gels, emulsions and
mixtures are to be pumped.
Series S pumps are suitable for CIP (Cleaning In Place) and conform to
USA 3A Sanitary Standard.
Operation
The positive displacement of the Series S pump is provided by non-
contacting, counter rotating tri-lobe or bi-lobe rotors within a fully swept
pump chamber. All Series S pumps are capable of bi-rotational flow
without modification.

Performance
The Series S pump range has twelve pump head displacements ranging
from 1.4 gallons/100 revs to 93.26 gallons/100 revs.
Flow rates up to 466 gpm
Differential pressures up to 290 psi
Port sizes from 1” to 6” diameter
High Volumetric Efficiency - The Series S pump offers high efficiency
transfer of low, medium and high viscosity pumped media. This
important aspect of performance is achieved by maintaining high
accuracy and repeatability of component part manufacture, thereby
maximizing shaft rigidity and minimizing the effects of thermal expansion
within the pump gearbox. This combination allows the optimum pump
head geometry to be achieved which, in turn, maximizes volumetric
efficiency.
Low NPSH - The Series S pump with standard port connections
has full through-bore inlet and outlet ports to International Standards.
This reduces inlet and outlet port losses, thereby lowering NPSH
requirements.
Basic Design
The Series S pump with its modular design giving a choice of 44
models, provides for greater application flexibility and cost effective easy
maintenance.
Pumphead - All metallic pumped media wetted components are
manufactured in 316L type stainless steel. The Series S in standard
specification has tri-lobe rotors available in three temperature ratings,
allowing the pump to be operated at maximum temperatures of 158°F,
266°F and 392°F for both process and CIP.
Shafts - 316L Stainless steel shafts are used for pressures up to 145 psi.
Higher pressures up to 290 psi are attained by the use of high strength
duplex stainless steel.
Gearbox - The Series S pump has a robust cast iron gearbox with a
universal design for models S1 to S4. This gives the flexibility of
mounting pumps with the inlet and outlet ports in either a vertical
or horizontal plane by changing the foot and its position. The Series S
models S5 and S6 have a choice of two dedicated gearbox castings,
which allows the inlet and outlet ports to be in either the vertical or
horizontal plane.

Pump overload protection
For essential overload protection to protect pump, drive unit and also
limit pressure build up within associated process equipment.
Pressure relief valve - supplied as an integral part of the pump and
not requiring any external pipework. The design is such that the valve
mechanism is isolated from the pumped media. Mechanical or
pneumatic operation is available for both pressure/safety and cleaning
bypass.
Pump Protection Unit (PPU) - supplied as an alternative to mechanical
relief valves. Incorporating micro-controller technology the PPU detects
and reacts to changes in load conditions.
Surface finish and coatings
To enhance standard surface finish or for hygiene purposes, the
pumphead and rotors may be electro polished. For abrasive applications
the stainless steel pumphead and rotors may be supplied with a
tungsten carbide coating or other surface hardening treatment to
increase wear resistance.
Interchangeable rotors
Mathematically defined profile and precision manufacture ensure
interchangeability of rotors with sealed involute splines giving accurate
position, location and positive rotor drive.
Option of bi-lobe rotors in stainless steel for handling products
containing large delicate solids, or bi-lobe rotors manufactured from
non-galling alloy for increased efficiencies. Elastomeric tri-lobe rotors
can also be offered where the application dictates.
Pumped media seals
The optimum primary seal can be chosen to match the pumped media
and duty conditions. Single or double mechanical seals include flushed
or aseptic variants. For arduous duties hard faced seal materials such as
tungsten carbide or silicon carbide can be used. Packed glands offer a
simple, low cost, and easy to maintain controlled leakage sealing
arrangement.
Pumped media wetted elastomers are EPDM, NBR, FPM all FDA
conforming or PTFE for chemical applications.
Heating / Cooling devices
These are primarily used for heating the pumphead so as to maintain
the pumped media viscosity and reduce risk of any crystallization/
solidification. They may also be used for cooling purposes when
required.
Connections
Comprehensive choice covering
Screwed male connections to all major standards including BSP,
DIN11851, IMDA/3A, ISS/IDF, NPT, Rdg, RJT, SMS, Tri-clamp
and more.
Flange connections to all major standards including ASA/ANSI150,
BS4504/DIN2533, BS10E and more.
Enlarged diameter and rectangular ports for handling very high
viscosity products.
Motorized pump units
Pumps may be supplied fully motorized with fixed or variable
speed drives including appropriate control systems if required,
mounted on either mild or stainless steel baseplates.
In addition to electric motor drives, hydraulic,
pneumatic, diesel or gasoline powered prime
movers can be fitted.
